Question

A store advertises a 45% discount on a $764 computer system. Find the sale price.

Answer 1

45% discount means that if the original price is 100%, then the new price is 45% lower. 100-45=55%. So you want to find out what is 55% of $764.

Answer 2

let the original sale price be s.
now after 45% discount, the sale price is $764.
so the equation becomes s-45/100*s=764
so 55s=76400
find s from this

Answer 3

@AnanyaManas The discount is on the original price of $764. 764 isn't the price AFTER the discount.
